Replicative Cell Senescence02:15

Replicative Cell Senescence

4.6K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

Telomeres and Telomerase

In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded...

Adaptive Mechanisms in Cancer Cells

7.4K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Abnormal Proliferation02:23

Abnormal Proliferation

5.4K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Area of Science:

  • Genetics and Molecular Biology
  • Oncology
  • Hematology

Background:

  • Telomere biology disorders (TBDs) stem from genetic variants affecting telomere maintenance.
  • These disorders lead to short/dysfunctional telomeres, causing bone marrow failure, organ damage, and immunodeficiencies.
  • TBDs are cancer predisposition syndromes with a 3-fold increased cancer risk.

Purpose of the Study:

  • To review recent advances in understanding solid malignancies in TBDs.
  • To highlight the urgent need for prospective studies on cancer surveillance and treatment in TBDs.

Main Methods:

  • Literature review of TBDs and associated solid malignancies.
  • Analysis of cancer incidence, mechanisms, and treatment outcomes in TBD patients.

Main Results:

  • Head/neck squamous cell carcinoma (HNSCC) risk is significantly elevated in TBDs (43-fold in AD, 276-fold in AR/XLR).
  • Standard cancer treatments show poor tolerance and outcomes in TBDs.
  • Mechanisms include chromosomal instability, DNA damage, immune deficiency, and clonal hematopoiesis.

Conclusions:

  • There is an urgent need for prospective studies to establish evidence-based cancer surveillance and treatment protocols for TBDs.
  • Understanding TBDs is crucial for managing associated cancer risks and improving patient outcomes.
